Herbert Xu 51c082514c crypto: xts - Handle EBUSY correctly 
As it is xts only handles the special return value of EINPROGRESS,
which means that in all other cases it will free data related to the
request.

However, as the caller of xts may specify MAY_BACKLOG, we also need
to expect EBUSY and treat it in the same way.  Otherwise backlogged
requests will trigger a use-after-free.

Fixes: 8083b1bf81 ("crypto: xts - add support for ciphertext stealing")
